CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of U.S. ProvisionalApplication No. 60/806,769, under 35 U.S.C. §119(e), filed 8 Jul. 2006,and U.S. Non-Provisional application Ser. No. 11/774,965 filed 9 Jul.2007, both of which are incorporated herein by reference in theirentireties.

FIELD

The claimed embodiments relate in general to methods and devices for thestorage and recall of audio content via an earpiece, and in particular,though not exclusively, for the storage and playing of music or verbalcontent on a system that is built into a headphone.

BACKGROUND

Present audio content playing devices are separated from the headphonesystem that normally contains the speakers (also referred to asreceivers). The reason for this has typically been that audio contenthas been stored on disks that require a separate playing system.However, even with the advent of storing audio content on non-disk RAM(Random Access Memory) storage systems, the audio content player hasbeen separated from the earpiece system (e.g., plug in headphones orearbuds). Combining the capacity for audio download and playing in anearpiece system is not obvious over related art since the userinteraction system (e.g., play button, keyboard system) does not readilyappear compatible with the size of an earpiece device and the difficultyof user interaction.

Additionally, no system currently exists for registration and downloadof audio content into an earpiece.

SUMMARY OF EXEMPLARY EMBODIMENTS

At least one exemplary embodiment is directed to a system forPersonalized Services delivered to a Personal Audio Assistantincorporated within an earpiece (e.g., earbuds, headphones).Personalized Services include content such as music files (for previewor purchase) related to a user's preferences, reminders from personalscheduling software, delivery and text-to-speech, speech-to-textprocessing of email, marketing messages, delivery and text-to-speech ofstock market information, medication reminders, foreign languageinstruction, academic instruction, time and date information,speech-to-speech delivery, instructions from a GPS system and others. APersonal Audio Assistant can be an audio playback platform for providingthe user with Personalized Services.

At least one exemplary embodiment is directed to a Personal AudioAssistant system that is included as part of an earpiece (e.g.,Headphone system). The Personal Audio Assistant is capable of digitalaudio playback, mitigating the need to carry a personal music player.Furthermore, a subscription-based service provides audio content to theuser through the Personal Audio Assistant. The type of audio content,which is automatically provided to the user, is based on the user'spreferences, which are obtained through a registration process.

The audio content, which is seamlessly downloaded to the Personal AudioAssistant in the background, is managed from a Server system and is onlyavailable on the Personal Audio Assistant for a predetermined period oftime or for a fixed number of playback counts. However, the user canpurchase any music file or electronic book directly from the PersonalAudio Assistant with a simple one-click control interface, storing thepurchased audio content on the Personal Audio Assistant as well asstoring the content permanently in a user storage lock-box location onthe Server system.

The system provides for audio content to be new and “fresh” each timethe user auditions the content. As such, the content is typicallyauditioned in a first-in: first-out scenario. In one such example, theuser has turned on the Personal Audio Assistant at 8:00 am and by 10:00am has auditioned 2 hours of content that were created for the user as amanifestation of the user's choices of their preferences of genre,artist, their demographics, day of the week, time of day and purchasehistory. The system also provides for the elimination of a particularsong or playlist in situ.

As the user's Listening History Envelope is updated based on experience,subsequent downloads will only contain content incorporating theserevised preferences. The Personal Audio Assistant provides for amplememory, thus permitting hours of uninterrupted playback without the needto download additional content from the server. When in need, thePersonal Audio Assistant automatically interrogates variouscommunication platforms as it searches for connections. Once aconnection is made, the Listener History Envelope file is uploaded tothe server, and a new set of personalized playlist content is downloadedto the Personal Audio Assistant. Accordingly, as the Personal AudioAssistant content is auditioned and thus depleted, the communicationssystem provides for constant replenishment.

In another embodiment, the Personal Audio Assistant also provides for anew set of business solutions to be offered to the music industry. Asthe personalized audio content is only available for audition for alimited period of time, and can not be sent to the user again from forweeks to months, the user's purchasing behavior can be demonstrated asspontaneous. The basic model of “Try before you buy” is the expectedoutcome. In another iteration, the distributor of the music can chooseto offer discounts, which can be time-sensitive or quantity-sensitive innature, in effect promoting greater purchase activity from the user.

In another iteration, while in audition a user can wish to place thedesired content in a hold status. The hold status forms the basis of a“wish list,” thus allowing the user to hold for future considerationaudio content while it is being auditioned. This content resides in thememory of the Personal Audio Assistant for a defined period, and isautomatically erased, or the user can do so manually. The selectedcontent will also appear on the user's computer via a URL address; hereit resides on the server ready for audition or purchase and download.

The system is designed to operate as simply as possible. Using a singlebutton, which has multiple contacts, the interface allows the user topurchase, delete, skip to next, and add to a wish list and even controla listening level.

In another iteration, the user can download their own music to thePersonal Audio Assistant for audition. The Personal Audio Assistantsystem is capable of text-to-speech processing and can interface withpersonal scheduling software to provide auditory schedule reminders forthe user. Auditory reminders relating to the user's medication scheduleare also generated by the system.

At least one exemplary embodiment includes input Acoustic Transducers(microphones) for capturing user's speech as well as EnvironmentalAudio. In further embodiments, stereo input Acoustic Transducers captureEnvironmental Audio, and, mixing it with the audio signal path, presentthe ambient sound field to the user, mitigating the need to remove theHeadphone apparatus for normal conversation.

Additional exemplary embodiments are directed to various scenarios forthe delivery and consumption of audio content. The Personal AudioAssistant can store and play back audio content in compressed digitalaudio formats. In one embodiment, the storage memory of the PersonalAudio Assistant is completely closed to the end-user and controlled fromthe Server. This allows for audio content to be distributed on atemporary basis, as part of a subscription service. In another iterationof the present embodiments, the storage memory of the Personal AudioAssistant is not completely closed to the end-user, allowing the user totransfer audio content to the Personal Audio Assistant from any capabledevice such as a Personal Computer or a Personal Music Player.

In at least one exemplary embodiment the Personal Audio Assistantautomatically scans for other Bluetooth®-enabled audio playback systemsand notifies the user that additional devices are available. Theseadditional devices can include a Bluetooth® video system, televisionsystem, personal video player, video camera, cell phone, anotherPersonal Audio Assistant and others.

In another iteration, the Personal Audio Assistant can be directlyconnected to a Terrestrial Radio receiver, or have such a receiver builtin to the system.

In another exemplary embodiment, a technique known as Sonification canbe used to convey statistical or other numerical information to aheadphone. For example, the user would be able to receive informationabout the growth or decline of a particular stock, groups of stocks oreven sectors of the markets though the Personal Audio Assistant. Manydifferent components can be altered to change the user's perception ofthe sound, and in turn, their perception of the underlying informationbeing portrayed. An increase or decrease in some level of share price ortrading levels can be presented to the user. A stock market price can beportrayed by an increase in the frequency of a sine tone as the stockprice rose, and a decline in frequency as it fell. To allow the user todetermine that more than one stock was being portrayed, differenttimbres and spatial locations might be used for the different stocks, orthey can be played to the user from different points in space, forexample, through different sides of their headphones. The user can actupon this auditory information and use the controls built-in to theheadphone to either purchase or sell a particular stock position.

Furthermore, specific sonification techniques and preferences can bepresented to the user as “themes” from which the user can select. Forexample, one theme might auralize the current trading price of one stockwith an ambient sine tone in the left ear, the price of another stock inthe right ear, their respective trade volumes as perceived elevationusing personalized head-related transfer function binauralization, andthe current global index or other market indicator as the combinedperceptual loudness of both tones. Such a scheme affords ambientauditory display in this example of five dimensions of financial datawithout compromising the user's ability to converse or work on othertasks. In another embodiment, the system affords users the ability tocustomize themes to their liking and to rapidly switch among them usingsimple speech commands. Additionally, the user can search the web fromvoice commands and receive results via a text to speech synthesizer.

In yet another exemplary embodiment the Personal Audio Assistant (PAA)functions as a dictation device for medical professionals for dictatingclinical information to a patient's medical record, or writeprescriptions for medication or devices. Conversely, the PAA canfunction as text-to-speech allowing the clinician to auditioninformation from a medical record, rather than reading. The PAA can saveconsiderable time preparing clinician interaction with a patient.

In another iteration, the Personal Audio Assistant can function as atool to locate other users of Personal Audio Assistant who share commoninterests, or who are searching for particular attributes of otherusers. Whereas the first user has stored specific personal informationin the Public Data memory of the Personal Audio Assistant, an example ofwhich might be related to schools attended, marital status, professionetc, or the first user can be in search of another user with theseattributes and whereas a second user of a Personal Audio Assistant comeswithin communication range of the first user, the individual PersonalAudio Assistants communicate with each other, access the personalinformation stored in each of their respective Public Data memories toascertain if these users have common interests. If a match occurs, eachunit can contain both audible and visual indicators announcing that amatch has been made and thus each user can start dialog eitherphysically or electronically via the environmental microphones.
